Ok my flow jet is set on right at 60psi and the air line going into the line is also set right at 60ish psi. It's putting out a soapy low low pressure mist. I know the chemical is good because I got it from another carwash friend that has it and his comes out crazy soapy!! Unlike mine. It's as almost if he has like a low pressure rinse type pressure.
Try to get the presoak liquid pressure up to 70. I prefer to separate the common air and add regulators for each pump. The Flojets last longer when they aren't being pushed at their maximum pressure all the time. Turning the air pressure down on the presoak stack will help too. Since there are no adjustments for each bay at the solenoids, you have to run the air pressure lower than the liquid.
He might have presoak coming through the high pressure pump at a reduced pressure. Coleman systems have that.
What is possible?
You can't pit 10lbs thru a 5lb sack and trying t put too much volume thru an .05 tip will kill the foam. I would start at 40 PSI for the liquid and 10 PSI for the air and perhaps increase the air to 20 PSI. Here is a video of Tire cleaner but PS is the same.
You rang?Another option would be to install foam guns and continue to use the Flojet. Typically foam guns use a much larger nozzle which reduces the amount of pressure required for the right amount of flow...
Can't believe I beat you to that suggestion, Cantbreak80?!
